The Liebert® PEX is the Next Generation Thermal Management Environmental Control System from Vertiv. It is a result of extensive research and development, conducted with leading environmental control experts, consultants and major corporations. A wide range of standard units offered from 20 KW to 100 KW in Upflow & Downflow Configurations.
The innovative belt drive system automatically provides the correct belt tension when operating speed has been reached, eliminating slippage and greatly extending belt life. No tools necessary to change the belt.
PEX units have achieved greater energy efficiency through the use of computer modeling techniques, combined with the synergistic matching of components.
The unit's inherent design, together with the ability to undertake all service work from the front of the unit rather than from the side or rear, results in minimal space requirements and the possibility of placing units side by side or against walls.
Three-bay and larger units may be constructed as your load capacity grows. The PEX units are formed on the basis of one-bay and two-bay building blocks, so you can rely on the PEX to grow with your requirements.
The front doors can be quickly and easily removed via the bayonet style hinge mechanism enabling components to be easily accessed. This significantly simplifies maintenance and servicing.
PEX units incorporate double-skinned inner side panels to increase structural rigidity and improve internal cleanliness.
The In-System-Programming (ISP) feature allows direct uploading of programming information from the Service Engineer's laptop, without the need to change-out memory chips.
Access to difficult sites and elevator limitations are no longer a worry. The PEX units can be delivered as separate modules and assembled on site. There is no need to disassemble for delivery, saving on both time and labour.
Proven, quality components are used throughout, and careful consideration given to their service requirements, thus ensuring minimum downtime.
The EC fan technology regulates airflow and reduces the fan input power. In-floor configuration further reduces energy consumption in downflow units. This significantly reduces energy consumption and provides longer component life. Managed through Liebert® iCOM controls, EC fans deliver airflow for the optimal operating conditions for IT equipment.
Liebert® PEX with Digital Scroll Technology is highly reliable and is designed to achieve efficiency with flexibility and to lower TCO. The use of digital scroll technology actively manages capacity modulation from 20 percent to 100 percent. During the loaded state, cooling units consume full load power. On the other hand, during the unloaded state, the units run freely, consuming only about 10 percent of the full load.
The teamwork mode in the iCOM Controller, a key feature of the Liebert® PEX, ensures efficiency by allowing multiple units to work together as a single system to optimize room performance.
The Infrared Humidifier has been a feature on Liebert® environmental control systems for over 45 years. Its rapid response and the ability to handle varying water conditions has made it an industry standard in applications that demand precise, particle-free humidity control.
This option a provides a second coil that utilises the central building Chiller system water supply. The unit can function either as a DX (compressorized) or a Chilled water system. During times when the chiller supply is available compressorized operation is eliminated, reducing energy costs. In addition this option can provide increased redundancy and flexibility to the environmental control system.
Optional GLYCOOL free-cooling system permits compressorless operation in colder ambient conditions.

High Energy Efficiency Ratio (EER). It basically depends on the heat exchange surface. Refrigerating circuits consume less energy.
High SensibleHeat Ratio (SHR). Sensible heat vs. latent heat. Technological applications require a high sensible heat discharge, without lowering room humidity too much, as it would need to be restored through a humidifier.
Site shutdown prevention
Extreme environmental conditions protection
Remote site conditions control
The Liebert MC Microchannel Condenser is an outdoor air-cooled condenser that provides higher efficiency, while using less refrigerant. Features such as variable speed fans, advanced controls and a microchannel coil make this system uniquely innovative.
